Comcast Center is a Live Nation-owned outdoor amphitheatre located in Mansfield, Massachusetts, 30 miles south of Boston, Massachusetts, USA at the intersection of I-495 and Route 140. The seating capacity is approximately 19,900. Approximately 7,000 are covered seats in the pavilion, 7,000 are open-air seats, and general admission is on the lawn. It was originally known as Great Woods Center for the Performing Arts until 1999 when Tweeter purchased the naming rights renaming the venue; Tweeter Center. However, due to recent financial struggles and possible bankruptcy, the Tweeter Home Entertainment Group opted out of its naming contract with the venue. Beginning in the summer of 2008, Comcast purchased the naming rights officially renaming the venue Comcast Center. The 2008 WBCN River Rave was the last event at the "Tweeter Center", the next day, there was another event from WZLX at the "Comcast Center". Because it is an outdoor venue, the Comcast Center is generally open May through September. The Comcast Center played host to the 23rd annual Farm Aid concert to support American agricultural workers. read more
